TILE-MAKING MACHINE Application filed October 19, 1927. Serial No.227,224.

This invention relates to machines employed in the use of themanufacture of dram tile T and Y connections and has for a prin-.

cipal object to provide a mandrel adapted to receive a section of hollowtile in its plastic condition, associated with which is a plunger framecarrying the shank section of the tile formed in a relatively hardenedcondition and adapted through the operation of the apparatus to forceone end of the shank through one side of the tile, thus causing anopening to be cut in the tile'about which the shank is securely weldedor attached upon the drying of the tile.

Another object of the invention is to provide a locking lever for themandrel, which when secured in locked position operatesto throw a clutchmounted on the machine arranged for controlling the movement of theplunger frame whereby to cause the operation of the same. 7

A still further object is to provide means for automatically disengagingthe clutch at the completion of the shank attaching 'action of theplunger frame so as to throw the same out of operative position.

An additional object is to provide an apparatus of this character ofsimple and practical construction, eflicient and reliable inperformance, enabling the shank section of draintile of this charactertobe formed in position on the tile in a uniform manner so that thefinished article will be of .an

identical formation, which is inexpensive to manufacture and operate andotherwise well adapted for the purposes for which the same is intended.

Other, objects and advantages reside in the special construction andcombination of the various elements comprising the invention,

reference being had to the accompanying drawings, wherein Figure 1 is aside elevational view.

Figure 2 is an end elevational view.

Figure 3 is a top plan view.

Figure 4 is a view in elevation, with parts shown in section of-theshank carrier for the plunger frame.

Figure 5 is a side elevational view of a complete T tile constructedthrough the use of our invention.

Figure 6 is a group view of the shank and tile section shown in detachedrelation.

Figure 7 is a longitudinal sectional view through the clutch mechanismtaken substantially along a line 77 of Figure 3.

Figure 8 is a detail of the clutch collar operating yoke. I

Figure9 is a detail'of the clutch control rod, and,

Figure 10 is a sectional view taken substantially along a line 1010 ofFigure 8 illustrating the automatic clutch release mechanism.

Referring to the drawings in detail, the invention comprises a frame 5forming a support for the apparatus at one side of which is pivotallymounted a mandrel 6 for horizontalswinging movement, the free end of themandrel being provided with a handle 7 and having notches 8 formedtherein intermediate its end engageable with guide rods 41 attached tothe frame whereby to guide the mandrel into the stationary section 10 ofa longitudinally split tile mold.

.The opposite section of the mold indicated at 11 is carried on apivotally mounted arm 12 swingable on the frame in a horizontal planeinsubstantially parallel relation with the mandrel 6.. V Y

The free end of the mandrel and arm 12 are adapted to be secured inlocked position by a pivotally mounted handle 13 having a' link 14attached thereto and operating a bellcrank 15 fulcrumed on the frame andoperatively connected with a slidably mounted clutch control rod 16. Therod 16 is inserted through a slotted opening formed in a supportingbracket 17 attached to the frame, the rod being yieldably retainedagainst upward movementby the pin 18 extending downwardly in the slottedopening in the bracket 17 and urged into engagement with the upper edgeof the rod by a coil spring 19. 'The under side of the free end of therod 16 is formed'with a shoulder 20 adapted to engage the end 21 ofiaclutch operating fork 22 pivotally mounted at 22' for horizontalswinging movement on the frame.

The opposite end of the fork 22 engages a clutch collar 23 slidablymounted on a drive 7 I.

shaft 24: and retained for rotation there with by a key 25, the movementof the collar in one direction operating to cause the engagement of apair of clutch plates 26, one

of said plates being carried on a hub 27 and to which a gear 28 isattached The hub and gear are attached to its adjacent clutch plate forfree rotation on the shaft, whereas the opposite clutch plate has itshub formed with a plurality of grooves 29 for receiving the fingers 30formed on the collar whereby to cause the rotation thereof with theshaft.

A coil spring 31 interposed between the collar and the adjacent clutchplate normally retains the same out of engagement therewith. The clutchplates are adapted to be locked into engaged position for positivefriction engagement with each other by means of latches 32 arrangedv formovement into locking position by means of rollers 33 slidabl-e upon theperiphery of the collar during the movement of the collar into suchengaging position. Adjusting screws 34 maintain the rollers 33 in properengaging position with the collar 23.

A gear 35 mounted on a counter-shaft 36 is operated through the drivegear 28, said gear 35 carrying a crank-pin operatively connected with apitman 39 and to which is attached a plunger frame 40 having verticallyextending guide rods 41 disposed for vertical sliding movement in guides42 attached to the frame 5.

The upper ends of the rods 41 are providec with a crossarm 43 from whichis suspended a punch mounting 44 having an annular collar 45 arranged atits lower end. A punch 46 is carried by the collar with its lower endextending therethrough, and supported upon the upper edge of the collarby means of pins 47 arranged at diametrically opposite sides thereof. Acoil spring 48 is interposed between the upper surface of the punch andthe mounting 44 yieldably urging the punch in downwardly extendedposition.

The upper face of the mold sections 10 and 11 are provided withsemi-circular notches indicated at 49 combining with each other to forma circular opening in the mold and about the edges of which upwardlyextending mold sections 50 are formed. Thus, when the sections 10 and 11are arranged in engaged position, the same constitutes a completed moldof a T-shaped formation within which the T drain tiles may be fitted.

A cam collar 51 is mounted on the countershaft 36 having a cam 52 formedat one sine Y thereof, adapted during the rotation of the shaft toengage a push rod 53 having its end attached to a bellcrank 54 disposedbeneath releasing the end 21 of the forkfrom engagement by the shoulder20 of the rod whereby to permit the spring 31 to move the collar 23 outof engaged position with respect to the clutch mechanism.

A section of drain tile of substantially cylindrical formation asillustrated in Figures 5 and 6 of the drawing and designated by thenumeral 55 may be placed on the mandrel 6 while in its plastic state andasection of tile indicated at 56 adapted to form the shank thereof andhaving its lower edge movement of the handle 13 so as to lock the partsin engaged position Wlll, as heretofore explained, throw the clutchmechanism intoengagement so as to cause the lowering of the punch frameand move the die mounting carrying the die 46 downwardly through theupper ends of the vertical extensions '50 of the mold so as to engagethe collar 45 upon theupper edge of the shank section 56 of the tile andthus press the same against the upper side of the tile section 55. Atthe same time the punch 46, which is of a slightly less diameter thanthe bore of the tile section 56 is inserted through said section to cutan opening within the upper edge of the tile section 55. The cam 52 istimed to throw the clutch'mechanism out of engagement upon the return ofthe punch frame to its uppermost position whereupon the pivoted arm 12and mandrel may be released from the handle 13 and the tile removedtherefrom'. The tile is then per mitted to drywhereupon the sections arepermanently sealed together.
